注浆是处治隧道塌方、突水突泥等地质灾害的有效手段，但对于岩体结构多样、结构面发育的富水断裂带，注浆理论及控制技术尚不成熟。基于富水断裂带内部岩体结构，建立了注浆概念模型，提出了优势劈裂注浆概念。基于广义宾汉流体本构方程，建立单一平板优势劈裂注浆扩散模型，推导了考虑浆液流变特征的优势劈裂注浆扩散控制方程。由方程可知，注浆速率、注浆压力及浆液黏度是影响注浆扩散的3个主控因素。深入分析了优势劈裂注浆过程中3个主控因素对注浆扩散的影响规律，基于此提出优势劈裂注浆控制方法，形成了注浆压力差异控制、控制液动态调节及注浆速率梯度控制3项关键技术，促使浆液在优势结构面内控制性扩散。研究成果成功应用于江西省某隧道断裂带塌方处治工程中，取得良好治理效果，对隧道断裂带地质灾害控制理论研究和工程实践具有一定指导意义。

Grouting technology was an effective technical means to control the geological disasters in tunnel construction, including collapse and inrush of clay and water. As for the complex structure and advantage joint development of the water-rich fault, the grouting theory and control technology had not been mature yet. Based on the typical internal rock mass structure of water-rich fault zone, a model of grouting was established. Then concept of advantage-fracture grouting was proposed. Based on the assumption of generalized Bingham fluid and single plate model of advantage-fracture grouting diffusion, a control equation for calculating the diffusion distance was developed considering the rheology behaviors of grout. It showed that the grouting diffusion distance was mainly controlled by the grouting pressure, grouting rate and the rheological parameters of grout. And the influence laws of the three factors on the diffusion distance were discussed. On this basis, the method of controlled grouting was established. Three key technology of grouting which were the grouting rate gradient control, gradient control of grouting rate and dynamic regulation of control-fluid were concluded, which impelled grout constrained diffusion in the advantage of structure. The research results were successfully applied to the tunnel fracture zone collapse in Jiangxi province and played a positive role in promoting the theoretical research and engineering practice of geological disaster.
